Hey guys, I have a few questions regarding Caching elements using the BGEO format. Im wondering what the advantages or disadvantages are when using the bgeo.sc compression vs bgeo without compression. Are there other benefits to using sc, other than smaller file sizes? also are there disadvantages, such as it taking longer for playback because of the compression on larger files? Lastly are there advantages or disadvantages in using other compression formats like gz and others? Appreciate any help on this topic. Thanks, Jordan
Hey, I recently played around with the network settings, among them was enabling jumbo packages. In the following tests i did, i noticed that Writing a VDB over the network was significantly slower than other formats(bgeo, begeo.sc, obj, etc.), for me on my current network writing a VDB is about 1/5 of the speed of other formats. Local write test show minimal difference, and when writing a vdb over the network it "waits for queued writes", it seems to be a network issue and not tied with the actually creating the VDB. My current solution is a post-frame script that moves the frame to the server after writing it locally and that seems to be about 3 times faster. But i was wondering if anyone could explain it or maybe have a better solution? I am defentlitely Houdini novice so i might just be completly be missing some env variable or the checkbox: MOAR SPEED!1!!one1! [ ]
Hey guys, I'm using a File Cache sop to cache a FEM mesh but I can't figure out how to write it's substeps. I'll use this later to collide with a flip simulation and since the FEM is moving pretty fast I need it's substeps to collide properly with the liquid. $FF doesn't work. I guess it saves integer only... not sure though. Any ideas on how to proceed? Thank's Alvaro
Hi, is there a way to write a point attribute in a Python Dop? I know that the usual way like objects.geometry() returns a read-only reference and only in a Python Sop you get it writable. But i want to change the attributes during the simulation. Thanks!
